Model: 7909-B
Overview
8mm | 24V | 120LEDs | 41.67cut | #7909-B | 1 SDCM Ultra-long LED strip light is part of the DENO 1 SDCM SMD Strips series, engineered around 1 SDCM LED strip. Key specifications: 2835, 120, 24V, 8 PCB, 3oz copper FPCB, cuttable 41.67mm. Every reel is produced on DENO's roll-to-roll line with 99.9% pure copper FPCB and ships CE, UL and RoHS compliant for architectural, retail and hospitality projects. OEM and ODM configurations of length, colour temperature and waterproofing are available on request.
Description
Engineered with 120 SMD 2835 LEDs per meter on an 8mm 3oz copper PCB, this 24V LED strip light delivers 767 lumens per meter. Single-bin sorting within 1 SDCM eliminates visible color shifts across adjacent spaces and large architectural lighting installations. Integrated constant-current circuitry maintains uniform brightness along continuous 15-meter single-feed runs or extended 30-meter dual-feed setups. Precise cut points spaced every 41.67mm combine with a 120-degree beam angle and dimming support for versatile fixture integration. Factory-direct wholesale project supply offers custom color temperatures, operating wattages, and protective ingress options on demand.
We use 99.99% gold wire, large-size chips, and thickened FPCB, backed by a 5-year warranty.

Applications
- Cove, wall-wash & perimeter lighting — Coves, recesses, wall-wash details and ceiling perimeters where a continuous, uniform line of light is required.
- Showroom & hospitality display lighting — Shelving, display cases, reception desks and signage backlighting in shops, showrooms and hospitality spaces.
- Kitchen & wardrobe under-cabinet lighting — Kitchen, wardrobe and furniture task lighting where the strip stays hidden and only the light is seen.
- Long corridor & warehouse runs — Long single-feed runs on 24V cover corridors, warehouse aisles and facade lines with fewer injection points and fewer power supplies.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 15W/m, 7909-B is a high-power SMD LED strip. Above roughly 14.4W/m the tape can no longer shed its own heat through the FPC alone — an aluminum channel is part of the luminaire, not an accessory.
Why high-wattage strips need a heat sink
- Aluminum conducts heat roughly 30× faster than the plastics, MDF or gypsum a strip is usually stuck to, so a bare high-power run traps heat under the tape.
- LED lifetime (LM-80 / TM-21) is driven by solder-point temperature Tc. Keeping Tc inside the datasheet limit — DENO strips are rated Tc ≤ 75°C — is what preserves the rated L70 lifetime and colour stability.
- Never run 14.4W/m or more coiled on the reel, inside a sealed plastic diffuser, or directly on wood, wallpaper or foam.
Sizing rule: FPC width vs channel inner width
- Channel inner width ≥ FPC width + 2mm. This strip is 8mm wide, so it needs at least 10mm of inner width.
- The 2mm clearance absorbs extrusion tolerance and lets the tape be seated or replaced without scraping the side walls or the wiring.
- A frosted or opal PC cover then diffuses the higher lumen output into an even, dot-free line instead of visible hot spots.

Recommended LED Channels
Mount this LED strip in a DENO LED aluminum profile for heat dissipation, physical protection and diffused, dot-free output.
This strip is 8mm wide, so it needs a channel with at least 10mm inner width (8mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
What are the key specifications of 7909-B?
7909-B: 2835, 120, 24V, 8 PCB, 3oz copper FPCB, cuttable 41.67mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
What colour temperatures and CRI options does this 1 SDCM LED strip offer?
This model is supplied as a 1 SDCM LED strip with high CRI options and the CCT range listed in the datasheet. DENO bins every batch for colour consistency, and custom CCT or spectrum combinations can be produced for project quantities.
Can DENO customise this 1 SDCM LED strip for a project?
Yes. DENO manufactures the 1 SDCM SMD Strips series as an OEM and ODM supplier: reel length, colour temperature, CRI grade, PCB width, waterproofing and private labelling can all be specified. Request a quote for lead time and project pricing.
What does 1 SDCM mean on a high CRI LED strip?
1 SDCM means every LED falls inside one MacAdam ellipse, so no visible colour difference exists between reels or between fixtures. Combined with Ra>90 and R9>50, this high CRI LED strip keeps white points matched across a whole project, which matters in retail, museum and hospitality installations where several runs sit side by side.
What limits how long an LED strip run can be?
Voltage drop and conductor current, not the LED itself. A long run LED strip combines low watts per metre, 2 oz or thicker copper and a higher bus voltage such as 24V, 36V or 48V to reach 20 m or more from one feed while staying inside a 3 percent drop.
